Another good reason for using our non-metallic containment shells: We have subsequently modified the first of three identical pumps for our customer to reduce both the power consumption and the external flush flow for bearing lubrication and magnet cooling significantly. The pump is a magnet drive centrifugal pump series SLM NVO, equipped with our largest hydraulics (400-400-500).
The metallic containment shell has been replaced by a non-metallic shell made of technical ceramics. Through the use of this new containment shell material, eddy currents are eliminated, reducing power consumption by 20 kW and the external flush flow by almost 90%.

This single volute untimed twin screw pump series DSP-2C is now pumping nearly 1,000 m³/h of hot asphalt at side for a large oil & gas customer. Klaus Union supplied two identical pumps, which are used for ship loading.

Die diesjährige DIAM Bochum ist vorbei und wir möchten uns ganz herzlich bei allen Besuchern, Kunden und Partnern für den Besuch auf unserem Messestand und nicht zuletzt für den intensiven fachlichen Austausch bedanken.

Die DIAM hat gezeigt: Das persönliche Gespräch ist auch weiterhin nicht zu ersetzen. Also bis bald, wir sehen uns auf der nächsten Messe!

SHARING OUR PASSION FOR PUMPS

Over the past two weeks, we hosted the first international technical training session at our headquarters in Bochum since the pandemic began. It was great to see our colleagues from different countries again in person – of course in compliance with strict hygiene regulations.

Many thanks to everyone for attending and for your valuable input. Hoping to see you again soon.

Klaus Union has delivered various vertically suspended pumps for ammonia applications of a new fertilizer plant in North Africa. The pumps are designed in both VS4 and VS6 design and come with different sealing types – simple stuffing box packings (following API 610) and magnet drives (following API 685), which are equipped with our new hybrid double containment shell.

This containment shell design combines two separate shells. The inner shell is a highly corrosion resistant metallic containment shell while the outer, secondary shell is a non-metallic containment shell made from heavy duty technical ceramics. The hybrid double containment shell meets API 685 § 3.66 “secondary containment system”.

Klaus Union pumps cover not only high temperatures of up to 450 °C (842 °F), but also temperatures as low as -200 °C (-328 °F). This is essential for cryogenic applications, where heat input has to be minimized. It is achieved through the use of non-metallic containment shells made of zirconium oxide, which are not electrically conductive. Due to this characteristic there are no eddy currents affecting the pump’s performance and in consequence, the pumping fluid is not being heated in the process.

Say hello to our new family members – our non-metallic containment shells made of zirconium oxide now cover an extended pressure range of up to PN 63. The new class of containment shells can be identified by their white color and the even further reinforced clamping ring.

For a new ethylene complex Klaus Union has supplied a global leading company with 55 pumps of different type for various applications. The vast majority of the pumps are manufactured in accordance with the requirements of API 685. These pumps of installation type OH2 (single and multi-stage) and VS4 will be installed outside, i.e. exposed to severe ambient conditions, e.g. very low ambient temperatures, and at the same time they will be exposed to pumping media with high temperatures of up to 200°C.
